Interests:I am an avid film user and digital user. I enjoy both formats and firmly believe they can live side by side.

Right Jazz! :D

Raw is the best to do most of your post processing but most labs require a JPEG or TIFF file. Once you are done working on your raw file you can export a full res JPEG. For a 60x40 I would contact the lab and ask them what their minimum file size they need, ie xxxx pixels by xxxx pixels for their posters. I know for a 24x36 inch poster my lab likes at least 3600x5400 but each lab may have different requirements.

They should be able to give you exactly what they need and what cropping you may need to do for it to fit the poster.

Yeah, the D3200 has a 24meg raw file. Not an issue with getting a 60x40. However, asking the lab what they need for the size is the best course. You might have given them a small file, or a low resolution. Meaning, something that is not 250 to 300 ppi. It's hard to tell without knowing what you offered them.

Thanks, Dennis.

Photography: 100 percent art, 100 percent technical. It takes a photographer to blend them into an image.

I gave the file to a friend who is a whiz on Photo shop and she played around with it, and I then sent the re-done file (not increased the size resolution though), and have sent off to 'Photobox" to print a 60x40cm poster.

Costing me £9, which for me will be interesting to see the finished product, and if its no good then its not too much money to lose, and if its fine - happy days !!

It seems like I've got my setting about right which was more what I was concerned about.
